VALl lE-G EAR.

SPECIFICATION forming part of Letters Patent No. 703,569, dated July 1, 1902.

Application filed June 13, 1901. Serial No. 64,388. (No model.)

To all whom it may concern: Be it known that I, KASBERG O. GEELE, a citlzen of the United States, residing at Finley, in the county of Steele, State of North Dakota, have invented certain new and useful Improvements in Valve-Gear; and I do here-. by declare the following to be a full, clear, and

exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.-

This invention relates to valve mechanisms for steam-engines; andit has for its. object to provide a simple and efficient. mechanism which is applicable to different styles of engines and wherein the valve will be operated in such manner as cient cut-oit. p V r A further object of the inv'entionis to provide a simple arrangementfor reversing the engine, other objects and advantages of the invention being understood from the following description. 4

In the drawings forming a portion of this specification, and in which like numerals.v of reference indicate-similar'parts in the several views, Figure l is a longitudinal sectional view through an engine equipped with the present invention. Fig. 2 is-an elevation of the valve. 7

Referring now to the drawings, there'is shown the invention as applied to a singleexpansion engine, wherein the cylinder 40 has a piston 41 provided with a rod 42. On the cylinder is a steam-chest 43, and between the steam-chest and the cylinder is a valvechamber 44, which communicates at its ends with the cylinder. disposed a reciprocatory valve 45, having the hollow plugs 46 and 47 adjacent to its ends and which project downwardly and into the upper portion of the cylinder.

The plugs46 and 47 are hollow and communicate with the steam;p ass ages 48 and 49 in thevalve. The passages 48=and 49 lead inwardly and then upwardly through the upper side of the valve and are adapted to register with the ports in the bottom of the steam-chest. There are two inlet-ports 50 and 50 and two outlet-ports 51 and 52, and the passage 48 is adapted to register alter- ,7 nately with ports 50 and 51, while the pasto secure amost effi-' .ment 36. f degree of lost motion with respect to the valve In the valve-chamber is sage 49 is adapted to register alternately with the ports 50 and 52, so that when one passage is in registry withan inlet-port the other passage will be in registry with an outlet-port. The ports 50 and 50 lead directly to the chest 56'and 57, which as the piston reciprocates alternately engage their respective plugs to shift the valve.

Thus when the piston has completed'one stroke it shifts the valve to reverse it, so that the return stroke will be made.

As'the direction of movement of the piswtons depends upon the position of the cut-on valve, itis only necessary to properly set the valve to insure the pistons traveling initially in the desired direction. Thus by properly ad= 'justinglthe valve the engine may be reversed. For shifting; the .valve manually it is providedwith a' stem 33, which extends through *a stuffing-box 34in the end of the valve-chamher; and connected to'rthe end of which stein isalever 35, which works over a notched seg- The inner end of the stem has a corresponding to the length of the path of movement of the valve, so that when the valve has been shifted the lever will not hold it against operation.

It will'be understood that in practice modifications ofthe specific construction shown may be made and that the valve mechanism may be applied to anystyle of engine to which her for shifting the valve manually, the stem having a degree of lost motion with respect to the valve.

2. An engine comprising a steam-chest, a valve-chamber between the cylinder and chest and communicating with the ends of the cylinder, a valve in the chamber and having studs projecting into the cylinder, passages formed through the valve for communicating the ends of the cylinder alternately with the chest, a piston in the cylinder, strikers carried by the piston for engagement with the studs to shift the valve, and means for manually shifting the valve initially.

3. Anengine comprisingacylinder,asteamchest, a valve-chamber between the cylinder and chest and communicating with the ends of the cylinder, a valve in the chamber and means for manually shifting the valve ini-' tially.

In testimony whereof I affix my signature in presence of two Witnesses.
